Currently, v4l2_pipeline_pm_use() prototype is:
int v4l2_pipeline_pm_use(struct media_entity *entity, int use)
Where the 'use' argument shall only be set to '1' for enable/power-on,
or to '0' for disable/power-off. The integer return is specified
as only meaningful when 'use' is set to '1'.
Let's enforce this semantic by splitting the function in two:
v4l2_pipeline_pm_get and v4l2_pipeline_pm_put. This is done
for several reasons.
It makes the API easier to use (or harder to misuse).
It removes the constraint on the values the 'use' argument
shall take. Also, it removes the need to constraint
the return value, by making v4l2_pipeline_pm_put void return.
And last, it's more consistent with other kernel APIs, such
as the runtime pm APIs, which makes the code more symmetric.

Using the field information attached to v4l2 buffers is not enough to
determine the type of field referenced by a DPB entry: the decoded
frame might contain the full picture (both top and bottom fields)
but the reference only point to one of them.
Let's add new V4L2_H264_DPB_ENTRY_FLAG_ flags to express that.

Avoid adding an extra columns when describing unions in the documentation.
That makes it much harder to read. See e.g. VIDIOC_QUERY_EXT_CTRLS.
Instead start off a union with 'union {' and end it with an extra row
containing '}'.
This leaves a lot more space for the description of the fields.
This formatting technique was used in a few places already, but this
patches fixes all remaining occurrences of 'union' in the media uAPI.

We currently have the following devnode types:
enum vfl_devnode_type {
VFL_TYPE_GRABBER = 0,
VFL_TYPE_VBI,
VFL_TYPE_RADIO,
VFL_TYPE_SUBDEV,
VFL_TYPE_SDR,
VFL_TYPE_TOUCH,
VFL_TYPE_MAX /* Shall be the last one */
};
They all make sense, except for the first: GRABBER really refers to /dev/videoX
devices, which can be capture, output or m2m, so 'grabber' doesn't even refer to
their function anymore.
Let's call a spade a spade and rename this to VFL_TYPE_VIDEO.

It is the vfrontporch of field 1 that is one half-line longer,
not the backporch.
The order of the vertical signals in an interlaced system is:
Field 1:
vsync
vbackporch
active video of field 1
vfrontporch + 0.5
Field 2:
il_vsync
il_vbackporch - 0.5
active video of field 2
il_vfrontporch
Interlaced systems that use HALF_LINE set the il_ fields as follows:
il_vfrontporch = vfrontporch
il_vsync = vsync
il_vbackporch = vbackporch + 1
So the total vertical blanking for field 1 is:
vsync + vbackporch + vfrontporch + 0.5
and for field 2:
vsync + vbackporch + 1 + vfrontporch - 0.5 ==
vsync + vbackporch + vfrontporch + 0.5
So each field has the same number of half-lines.

This introduces the required definitions for HEVC decoding support with
stateless VPUs. The controls associated to the HEVC slice format provide
the required meta-data for decoding slices extracted from the bitstream.
They are not exported to the public V4L2 API since reworking this API
will likely be needed for covering various use-cases and new hardware.
Multi-slice decoding is exposed as a valid decoding mode to match current
H.264 support but it is not yet implemented.
The interface comes with the following limitations:
* No custom quantization matrices (scaling lists);
* Support for a single temporal layer only;
* No slice entry point offsets support;
* No conformance window support;
* No VUI parameters support;
* No support for SPS extensions: range, multilayer, 3d, scc, 4 bits;
* No support for PPS extensions: range, multilayer, 3d, scc, 4 bits.

Since the uapi does not contain the num_ref_idx_active_override_flag,
drivers for decoders that do not parse slices themselves don't know
how to choose between the num_ref_idx_l[01]_default_active and the
num_ref_idx_l[01]_active override fields.
Instead, userspace must set the override fields to the default values
if the slice does not have the num_ref_idx_active_override flag set.
The drivers will then always enable the override internally and ignore
the default fields completely.

Merge tag 'drm-next-2019-09-18' of git://anongit.freedesktop.org/drm/drm
Pull drm updates from Dave Airlie:
"This is the main pull request for 5.4-rc1 merge window. I don't think
there is anything outstanding so next week should just be fixes, but
we'll see if I missed anything. I landed some fixes earlier in the
week but got delayed writing summary and sending it out, due to a mix
of sick kid and jetlag!
There are some fixes pending, but I'd rather get the main merge out of
the way instead of delaying it longer.
It's also pretty large in commit count and new amd header file size.
The largest thing is four new amdgpu products (navi12/14, arcturus and
renoir APU support).
Otherwise it's pretty much lots of work across the board, i915 has
started landing tigerlake support, lots of icelake fixes and lots of
locking reworking for future gpu support, lots of header file rework
(drmP.h is nearly gone), some old legacy hacks (DRM_WAIT_ON) have been
put into the places they are needed.

The existing documentation was incorrect and did not correspond
to how actual codec drivers implemented this.
Update the documentation to explicitly specify what is actually
expected.

Due to complexity of the video decoding process, the V4L2 drivers of
stateful decoder hardware require specific sequences of V4L2 API calls
to be followed. These include capability enumeration, initialization,
decoding, seek, pause, dynamic resolution change, drain and end of
stream.
Specifics of the above have been discussed during Media Workshops at
LinuxCon Europe 2012 in Barcelona and then later Embedded Linux
Conference Europe 2014 in Düsseldorf. The de facto Codec API that
originated at those events was later implemented by the drivers we already
have merged in mainline, such as s5p-mfc or coda.
The only thing missing was the real specification included as a part of
Linux Media documentation. Fix it now and document the decoder part of
the Codec API.
